Hi,
Honestly I didn't faced this issue before.
Maybe inside the variable at the OS is listed a library that can't be pre-loaded and linker will try to load libraries listed in the LD_PRELOAD variable before others are loaded. Take a look inside your .bashrc or .bash_profile environment where the LD_PRELOAD is set and remove that library from the variable.

Btw how are you testing this model?

As I mentioned in the README file it could be tested only within php like below (example)
`php cvc.php ./dataset/train/ABAP/zcl_3_factory.clas.abap`

p.s. if you will face issue to run composer/installation of php-ml library I can pack this lib and just send as additional archive. Example how it works in the attachment

Unfortunately, this submission has been disqualified as we were unable to rebuild or run it.

This is an important message regarding your submission. The following issues have been discovered during preliminary testing:
ld.so: object './model/libtglang.so' from LD_PRELOAD cannot be preloaded (invalid ELF header): ignored.

You can provide further clarifications within the next 24 hours.
